抄録/ポイント： 電離層電子密度は,地磁気静穏日中の日没後に増大すると予想される。本論文では,比較的静かな地磁気条件下で,中国の低緯度で朝に起こる異常大規模電離層TEC枯渇構造について報告する。>35°の広い経度範囲で生じた枯渇構造は,~250m/sの速度においてより高い緯度に向かって発達した。2018~2020年のデータを用いた統計解析は,このような大規模な昼間TEC枯渇が主に夏季(主にKp<3)で生じ,約16~30°Nで大きな強度を持つことを示した。磁気ディップ赤道の近くと離れた観測所での地磁気ΔH測定は正の値を示し,これは西電場からの可能な寄与を除外した。多重イオノゾンデからの観測は,TEC枯渇中の正味の下方プラズマ輸送を明らかにした。早朝の時間の間に,下向きのプラズマ輸送を誘発する可能性がある,強化された極向きの中立風は,大規模な朝のTEC枯渇の駆動において,主要な役割を果たすと推測した。Copyright 2022 Wiley Publishing Japan K.K.
